My JBL Flip 4 will not charge. I had it for a while until the charge went dead and it will not charge. I plug it in and leave it for a couple hours and when I come back to check on it, it hasn’t charged at all.
If your JBL Flip 4 speaker will not charge or won’t hold a charge, see the JBL Flip 4 Will Not Charge Or Won’t Hold a Charge problem page for possible causes and solutions.
